Application filed August 23, 1911.

To all whom it may concern Be 1t known that we, THOMAS MoFnnLY and LANDIS RoMioK, citizens of the United States, and residents of Folcroft, Delaware county, Pennsylvania, and Niles, Trumbull county, Ohio, respectively, have invented certain Improvements in Bran and Middlings Finishers, of which the following is a specification.

One object of our invention is to provide a machine which will successfully and efiiciently remove glutinous middlings from bran or broken wheat without pressure or other destructive action on said particles; it being especially desired that the machine shall be of such design that practically all of the valuable middlings shall be removed from the bran or other material under treatment. 1 r

We further desire to provide a machine for doing the work above noted with novel means for causing the disengagement of the particles of middlings and gluten from the bran, etc., to which they are attached.

These objects and other advantageous ends we secure as hereinafter set forth, ref erence being had to the accompanying drawings, inwhich Figure 1, is a longitudinal vertical section of a machine constructed according to our invention, and Figs. 2 and 3 are transverse vertical sections respectively on the lines aa, and 39-72, Fig. 1. I

In the above drawings the machine is shown as providew ith base members 1 on which 1s mounted a frame consisting of two 7 end members 2 and 3 connected by a pair of top members a and a pair of botom members 5. Carried by the end members 2 and 3 of the frame are bearings 6 and 7 for a shaft 8 which may be driven from any suitable source of power.

Within and carried by the frame is a substantially cylindrical casing concentric with the shaft 8 and formed in two sen1i-cylindrical parts 9 and 10 each provided with outwardly extending flanges along its longitudinal edges; there being bolts in said flanges for connecting together the said two sections.

It is to be particularly noted that the sections 9 and 10 are of different diameters and as shown in the drawings, the upper section has the larger diameter, so that there Specification of Letters Patent.

are formed two horizontal ledges 11 along the lines of its junction with the lower section and by reason of the difference in diameter of said sections the volume of the upper section is materially greater than that of the lower.

At the end of the machine adjacent the part 2 of the frame is a hopper 12 for the reception of the material to be treated, there being an opening 13 at the top of this hopper through which a discharge spout may be connected, but shown in the present instance as closed by a cover 14. This hopper opens into one end of the main casing 910 and there is a discharge opening 15 at the opposite end of said casing provided with a discharge spout 16 normally closed by a weighted valve 17-.

Upon that portion of the shaft 8 extending into the hopper 12 are mounted two conveying blades 18, although it is obvious that any other suitable'number of blades may be used for the purpose of forcibly transferring the material from the hopper into the adjacent end of the casing. On the main portion of the shaft within the casing are mounted a number of'sets of radially projecting beater arms 19 and 20 each preferably having one face inclined so that it assists in conveying material from the hop per through the casing to the discharge end thereof and at the same time so engages the material as to give this a rotary motion relative to theshaft.

We preferably so proportion the arms that those indicated at 19 for example, are shorter than the arms 20 which project opposite them in the same line from the opposite side of the shaft, and in the present 7 instance we have illustrated adjacent pairs of the arms 19 and 20 as spaced apart and displaced 90 relatively to each other.

Formed integral with, or otherwise fixed to the cylindrical casing 10 are mounted a operating conditions, is drivenat a suitable well as with one of the ledges 11, with the result that the granules of gluten adhering to saidbran are forcibly detached without beingin any way injured, as would be the case were they subjected to a crushing pressure. 1

It is especially tobe noted that by our mas chine the material under treatment is at no time crushed or ground, but is forcibly thrown against the plane facesof the abutments interposed in the path and provided by-Lthe abutments 21 and the ledge 11.

We have found that in order to secure the best results, the velocity of rotationofthe.

material under treatment should be. alter,-

-nately increased and decreased instead of I being uniform as would be the case'if such greater'diameter than the section 9, the vio material were permitted to rotate or whirl in the casing under the action of the arms alone and that by making the section 10 of lently rotating or whirling mass of material changes its velocity as it passes from one section to the other and caused the machine to work at the highest efficiency.

4 Owing to the inclined faceprovided on each of the beaterarms, the material under treatment is gradually moved from the hopper end of'the casing to the-discharge end thereof and finally enters thespout 16, from l which it is automatically discharged by the swinging outward of the valve 17 when the (l'opies of thispatent may be obtained for five cents each, by addressing the Commissioner of Patents,

pressure against it becomes sufficiently great. This material discharged consists of a mechanical mixture of clean bran andgranules of middling and gluten and it is is thereafter subjected to any suitable process finisher of a casing consisting of semicylindrical top and bottom sections of which the bottom section is smaller'in diameter than the top section and has laterally extended flanges along its longitudinal edges forming plane ledges Within the casing; a series of abutments extending inwardly from the inner surface of said casing; a rotary shaft extending through the casing; with beater arms on the shaft placed to be operative between the abutments and formed to convey material through the casing.

In'testimony' whereof, we have signed our names to this specification, in the presence of two subscribing witnesses.
